"Be very conservative, because it could be very rough out there,"
Trump said. "And who can fix things better than me?"

The Republican presidential front-runner discussed the stock
market while bemoaning the US's nuclear deal with Iran, which he
said would make the Middle Eastern country very rich.

"If Iran were a stock, buy it. OK? By the way, speaking of stock:
You see the bubble, a little bubble. It's starting to go a little
bad. Some bad numbers coming out. Some really bad things. And you
better be careful. Be careful," Trump said at the Burlington,
Vermont, rally.

In a Fox News "On The Record" interview that
aired Thursday evening, Trump also said China's economy was
resting on a "little bit of a bubble."

"They're sitting on a little bit of a bubble — it could be a lot
of bubble," Trump said. "But we're sitting on a bubble also. So
China's [economy is] going to go up 6.5% and we're going up 2%.
And we're sort of satisfied at 2%. I'm not satisfied, but a lot
of other people are satisfied. And we shouldn't be satisfied with
that number. We should be doing much better."

"The buck stops with the president," Trump replied. "He is in
charge of things. And we've had a very, very, mild uptick. It's
been, I guess it's been the slowest [recovery] since the [Great]
Depression in terms of going up."

As he did
earlier in the day, Trump also took a shot at Macy's, which
just announced it was cutting thousands of jobs. The
department-store giant announced last summer that it would phase
out its Trump-branded products, after the billionaire ignited a
national firestorm with his provocative comments accusing Mexico
of sending violent criminals across the US border.

"I see Macy's is doing very, very poorly," Trump said on Fox
News. "Their stock is down tremendously. So many other companies
are doing poorly. So the stock market now is catching up with the
real economy."

He continued: "The stock market's been taking a big hit for quite
some time now. So, ideally, I hope that's not happening. But it's
obvious that we're not doing very well as a country in many
respects. We're not doing well with ISIS and we're not doing well
with anything. I mean, where are we doing well?"
